WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 367,466, dated August 2, 1887.

Application filed November 17, 1886. Serial No. 219.171. [No model.)

To (LZZ 10710177, it ntay concern.-

Be it known that I, ABsALoir TEMPLETON, a citizen of the United States, residing at Lone Grove, in the county of Llano and State of Texas, have invented certain new and useful Improvements in VVagon-Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Myinvcntion has relation to wagon-brakes; and it consists in the novel construction and arrangement of its parts, in combination with the running-gear and body of the wagon, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of a wagon with my attachment secured thereto. Fig. 2 is a side elevation of the front rocking bolster with my kingbolt attached. Fig. 3 is a crosssection of Fig. 2 cut on the line 3 3 Fig. 4 is a cross-section of Fig. 2 cut on the lines 09. Figs. 5,6,7, and 8 are detail views.

My invention is described as follows: To the lower face of the front rocking bolster of the running-gear of anordinary wagon I attach my king-bolt 1. This king-bolt 1 has a cylindrical T-head, 2, which is partly embedded in the lower face of the bolster 3 by means of bands, bolts, and nuts 4. In order to prevent the groove or depression made in the lower face of the bolster 3 from wearing, it is lined with a heavy sheet of metal, 5, which is secured in place by bolts or other substantial means. On either side of the front end of the wagonbed A, and just over the rocking bolster 3, is attached my front standard-guards, 6, which have a V-shaped recess or notch, 7, in them, the wider end of said recess being up, that allows the said standards 8 to swing forward a few degrees when the wagon starts down hill, but only allows the standards to swing forward a short distance. Toward the rear end of said wagon-bed, and on either side and a little distance in advance of the rear standards, is secured the device B,drawing the brake back against the periphery of the hind wheels. This device B consists of a lever, 9, having perforations in its upper end and a ratchetwheel on its lowerend, the teeth of which mesh with the cogs or teeth on a ratchet-rod, 10. This lever 9 and ratchet-rod 10 are incased in an iron case, 11,which is securely bolted to the outer face of the wagon-bed. The lower end of the ratchetrod 10 has pivoted to it an extension, 12, the lower end of which works in the eye 13 of a threaded bolt, 14, which passes through and is secured in a beam, 15, to either side of which beamis secured thefrictionblocks 16. Passing perpendicularly through said beam 15 are bolts 17, which are secured in said beam by nuts or other equivalent means. The upper end of these bolts 17 are split, and in this split is pivoted a bar, 18, which is bolted or otherwise secured to the side of the wagonbed equidistant between the front and rear wheels.

The devices above described are attached to either side of the wagon-box. In the upper end of the lever 9 is secured a rod, 19, which extends forward, and the front end is securedin the eye of a bolt, 20, which is secured in the upper end of the front standards, 8, by nuts or other equivalent means. The coupling-tongue 21 has in its front end a slot, 22, instead of the usual perforation.

My brake is automatic and operates as fol lows: hen a wagon starts down hill, the gravity throws the weight of the bed forward, and the slot 22 in the front end of the coupling tongue 21 allows the hind part of thewagon to run forward and close up toward the front wheels the length of the slot 22. This tilts the rocking bolster 3 and the standards 8 forward until they come against the front edgeof the recess or notch 7 in the staudard-guardsG. This movement also brings the hind wheels near the friction-blocks 16, and it also forces-the upper end of the lever 9 forward, and as it is at-,

tached to the rod 19, above shown, and the cogs just the exact amount of pressure against the periphery of the wheels that is needed. \Vhen thewagon reaches level ground, the hind wheels fall back at once, and the pressure is relieved and the wagon is unlocked.

Having described my invention, whatI claim as new, and desire to secure by Letters Patent, 1s-

1. In an automatic wagon-brake, as above described, the combination of the king-bolt 1, having the cylindrical T-head 2, the lining 5, secured in the depression in the lower face of the bolster 3, the band, nuts, and bolts 4, sub-. stantially as shown and described, and for thepurposes set forth.

2. In an automatic wagon-brake, as above described, the combination of the rocking bolster 3, standardsS, eyebolts 20, secured in the upper end of the said standards, rod 19, the front end secured in eye of said bolts 20 and its rear end in the upper end of the lever 9, lever 9, pivoted in case 11, case 11, secured to the wagon-bed A, ratchet-rod 10,working in said case 11, extension-rod 12, one end pivoted to the lower end of ratchetrod 10 and the other working in the eye 13 of the bolt 14, which passes through the beam 15, beam 15,

carrying on either end the friction-blocks 16, bolts 17, secured perpendicularly in said beam 15, bar 18, its lower end pivoted to bolts 17 and its upper end secured tosaid wagon-bed A, substantially as shown and described, and for the purposes set forth.

3. In an automatic wagon-brake, as above described, the combination, with the rear running-gear having the slotted coupling-pole 21 and the wagon-bed, of the locking device B, secured to said bed, rod 19,secured to said look ing device and front standard, 8, standards 8, secured in the rocking bolster 3, and the standard-guard 6,having the V-shaped recess 7, substantially as shown and described.

4. In an automatic wagon-brake, as above described, the standard-guards 6, secured to either side of the wagon-bed and having the V-shaped recesses 7, embracing the front standards, substantially as shown and described, and for the purposes set forth.

In testimony whereof I affiX my signature in presence of two witnesses.

ABSALOM TEMPLETON.
